How to Get the Right Document Scanner
A document scanner can be indispensible if you need to scan something and to send it as a fax, print it or save a copy of it on your computer. Scanners are is also idea for scanning photos, in order to retain the original (and keep it safe), as well as to make photo edits or improvements to it and use it for a digital scrapbook.
There are several kinds of scanners available on the market in various price ranges. When you are considering buying a document scanner, look at some of the key features to see if the include what you need.
Some of the features to look into include: the resolution, whether you need a flatbed scanner or an all in one document printer/scanner/fax machine.
First of all, the optical resolution of a document scanner should be as high as possible, ensuring that the quality of the scanned document will be high. The minimum resolution per inch should be 1200X1200 dpi. There are document scanners with a double resolution or even higher. The higher the resolution, the more you can enlarge the document without getting a blurred image.
Take into account the bit depth because a scanner with a higher the bit depth can recognize more detail and colors, allowing for accurate scans. 40 bits or more is the amount you’ll find in a good document scanner.
If you can find the required specifications or technical specs., see if they fit the type of computer you will use the scanner with.

Another important consideration is the type of connection that the device uses. Several types of ports or connections are used for periferals such as scanners, including USB, Firewire or the parallel port. Check to see that you computer has the ability to connect to whichever scanner model you are interested in.
Other operating system information may be something you need to know, such as the version of your operating system and other minimum system requirements.
Scanner sizes vary with some having the ability to scan up to A4 size (letter size), and others can handle larger sizes. Some document scanners will scan portions of a document and then reassemble them to create large sized scans.
Check to see what software may come with a scanner. The better software you can get will make scanning much easier.
Special attachments or adapters can also work on some scanners, such as those that will allow you to scan photographic negatives, filmstrips, or 35mm slides.
When you are interested in scanning black and white documents, check out the number of shades of gray that the scanner has.
The scan mode may also interest you: this may be single, duplex pass or both. If the size or the weight matters, find out details about these. However, the weight and the size of a document scanner do not influence the quality of the device.
Finally, find out about the manufacturer’s warranty details, especially for higher priced document scanners.

Do you know of a portable document scanner that don’t need to be connected to a computer to scan a document
In other words, I am looking for a gadget that after scanning the document it saves it in a temp memory in the scanner. Then you connect it to the computer to upload as a pdf or word doc.

how big is the document you're trying to scan? they make pen scanners, they work good for students that only need certain text and when you only have limited funds and a library down the street works well. anywho hope that helps.

berrizalina,
A stand-alone scanner is an awesome concept – I’ve heard that they exist, but will have to research them more and get back to you.
